It is a top view which shows the usage example of the adapter for rulers in a prior art.

  Hereinafter, the form for implementing this invention is demonstrated using FIGS. In the following description, “portable marnoco 4”, “wood W”, and “cutting” will be described as examples of “portable processing machine”, “processed material”, and “processing”. In the following description, “up, down, front, back, left, right” indicates the directions of up, down, front, back, left, right described in the above-described drawings. The guide device 1 is used when the wood W is cut into a straight long distance using the portable marnoco 4. Below, this portable Maruko 4 and the guidance apparatus 1 are demonstrated separately.

  First, the portable marunoco 4 will be described (see FIGS. 1 and 2). The portable marnoco 4 is mainly composed of a substantially rectangular base portion 10 that comes into contact with the upper surface of the wood W, and a processing machine main body portion 11 supported on the upper surface side of the base portion 10. The processing machine main body 11 is provided with a saw blade 12 as a processing tool and a saw blade case 13 that accommodates and covers the periphery of the upper half of the saw blade 12 in a substantially half-circumferential range.

  The saw blade case 13 is supported by the base portion 10 at two locations on the front side and the rear side in the processing direction. The front side of the saw blade case 13 in the processing direction is supported so as to be vertically swingable via a vertically swinging support shaft 15 of a tilt support bracket 14. The rear side of the saw blade case 13 in the processing direction is supported on the base portion 10 side via the depth guide 16. The depth guide 16 is a strip-shaped guide member that is curved in an arc shape, and is provided in a state of rising upward along the back side of the saw blade case 13.

  The vertical swing position of the processing machine main body 11 is fixed by tightening a threaded fixing lever 17 on the back surface of the saw blade case 13 through the depth guide 16. By loosening the fixing lever 17 and moving the rear portion of the saw blade case 13 up and down while guiding it with the depth guide 16, the processing machine main body 11 swings up and down via the front vertical swing support shaft 15. Thus, the protruding amount of the saw blade 12 toward the lower surface side of the base portion 10 and thus the depth of cut of the saw blade 12 can be adjusted.

  Although not visible in the figure, the portion of the saw blade 12 protruding to the lower surface side of the base portion 10 is covered with an opening / closing cover. This open / close cover is brought into contact with the end of the wood W and is relatively opened as the portable marvel 4 moves in the processing direction. The open / close cover is opened, the saw blade 12 is exposed, and the exposed portion is cut into the wood W. Further, the saw blade case 13 is supported on the base portion 10 in a state in which the saw blade case 13 can be tilted left and right in the processing direction via the front and rear left and right tilt support shafts 19.

  In FIG. 1, only the front left and right tilting support shaft 19 is visible. Angular plates 20 are provided at the front portion and the rear portion of the base portion 10. When the front and rear fixing screws 21 are tightened, the front part and the rear part of the saw blade case 13 are fixed to the front and rear angular plates 20, respectively, and the left and right tilting with respect to the base part 10 of the saw blade case 13 and the processing machine main body 11 is performed. The position is fixed.

  By fixing the saw blade case 13 and thus the processing machine main body 11 around the front and rear left and right tilt support shafts 19 at a position tilted left and right by a certain angle, the wood W can be cut at an angle. On the back side of the saw blade case 13, a reduction gear portion 22 in which a gear train is housed in a substantially cylindrical gear case is integrally provided. A drive motor (electric motor) 23 is coupled to the reduction gear portion 22.

  The reduction gear unit 22 and the drive motor 23 are provided in a state of protruding leftward from the back surface of the saw blade case 13. In the vicinity of the joint between the reduction gear portion 22 and the drive motor 23, a handle portion 24 that is gripped by the user is provided. The handle portion 24 has a loop shape extending from the upper surface of the reduction gear portion 22 to the rear surface in the machining direction. When the trigger type switch 25 provided on the inner peripheral side of the handle portion 24 is pulled, the drive motor 23 is activated.

  The rotation output of the drive motor 23 is output to the spindle through the reduction gear portion 22, and the saw blade 12 rotates. A ruler mounting portion 26 for mainly mounting a parallel ruler (not shown) is provided at two locations on the front and rear sides of the base portion 10. Both ruler mounting portions 26 are mainly composed of groove portions on the left and right along the width direction of the base portion 10 and perpendicular to the machining direction. A fixed lever 28 with a screw is provided in the hole.

  The parallel ruler can be attached to the base portion 10 by inserting the support arm of the parallel ruler into the two ruler attachment portions 26 at the front and rear and tightening the fixing lever 28. This parallel ruler is attached in parallel with the saw blade 12, and the portable saw blade 4 is moved in a state of being in contact with the end face of the wood W, so that the saw blade 12 is accurately fixed with respect to the end face of the wood W with a certain width. Can be cut by moving to. The portable marnoco 4 is configured in this way.

  Next, the guide device 1 will be described (see FIGS. 1 to 7). This guide device 1 includes a long ruler plate 2 that is fixed on a top surface of a wood W and a ruler adapter 3 for guiding a portable marvel 4 in the processing direction with respect to the top surface of the ruler plate 2. It consists of and.

  The ruler plate 2 is a drawing material having a long rectangular flat plate shape, and a guide convex portion 30 is provided over the entire length of the upper surface of the ruler plate 2 at the center in the width direction or toward the left side. A sliding member 31 for enhancing the slidability with respect to the base portion 10 of the portable maroon saw 4 is similarly attached along the left side of the guide convex portion 30 over the entire length. A sliding member 32 for enhancing the slidability with respect to the base portion 10 is also attached to the right end portion of the ruler plate 2 on the right side of the guide convex portion 30 over the entire length (see FIGS. 1 and 2).

  By attaching the sliding material 31 and the sliding material 32 to the upper surface of the ruler plate 2, it is possible to reduce the friction with respect to the base portion 10 and to easily move the portable marnoco 4. On the other hand, a rubber anti-slip material 33 for preventing the wood W from slipping along the left and right sides of the guide protrusion 30 and the right end of the ruler plate 2 on the lower surface of the ruler plate 2 It is pasted over. By placing the ruler plate 2 on the upper surface of the wood W with these anti-slip members 33 in contact with each other, the ruler plate 2 is prevented from being displaced during cutting, and the smooth movement of the portable marnoco 4 is realized. Is done.

  As shown in FIG. 1, the anti-slip material 33 on the right end side is attached so as to protrude from the right end portion of the ruler plate 2 with a certain width, and the position of the saw blade 12 is located on the anti-slip material 33 on the right end side. It also has a function as a blade plate that indirectly points to. An auxiliary recess 34 having a groove shape that opens upward is provided at the left end of the ruler plate 2 over its entire length. On the right side of the auxiliary recess 34, an engagement recess 35 is also provided over the entire length. The function of the engagement recess 35 will be described later. The ruler plate 2 is configured in this way.

  On the other hand, the ruler adapter 3 includes base members 40 that are adjacent to each other so as to form a pair, and a connector 60 that connects the base members 40 (see FIGS. 3 to 7). In addition, this base member 40 makes a pair in front and rear. Therefore, description of one base member 40 will be omitted, and description of the other base member 40 will be omitted. The same applies to the rattling prevention mechanism 50 and the rod 70 described later.

  The base member 40 has a flat plate shape along the processing direction, and is attached so as to be movable along the upper surface of the ruler plate 2 while being superimposed on the upper surface of the ruler plate 2. A mounting groove 41 into which the first piece 72 of the rod 70 can be inserted is provided on the upper surface of the base member 40 along a direction (left-right direction) orthogonal to the moving direction (front-rear direction) of the base member 40. (See FIG. 7). A boss 42 is provided on the upper surface of the base member 40 so as to straddle the attachment groove 41. The boss 42 is provided with a through hole 42 a into which the fixing screw 43 can be screwed.

  A guide recess 44 that can be fitted into the guide protrusion 30 of the ruler plate 2 is provided on the lower surface of the base member 40. A mounting groove 45 is provided on the lower surface of the base member 40 in parallel with the guide recess 44. A through hole 46 is provided on the upper surface of the base member 40 so as to penetrate the mounting groove 45. A fixing screw 47 to which a nut 48 can be screwed can be inserted into the through hole 46.

  The rod 70 is formed by bending a strip having a constant width into a crank shape at the center in the longitudinal direction, and includes a first piece 72 on the left side of the bent portion 71 at the center and a second piece 73 on the right side. . The first piece portion 72 and the second piece portion 73 are shifted from each other in the plate thickness direction by substantially the plate thickness. The second piece 73 has a protrusion 74 formed thereon. With this projection 74, the amount of insertion of the second piece 73 into the ruler mounting portion 26 of the portable marvel 4 can be regulated.

  Then, with the first piece 72 of the rod 70 inserted into the mounting groove 41 of the base member 40, the fixing screw 43 is screwed into the through hole 42a and tightened. Then, the tip of the fixing screw 43 that has advanced from the through hole 42 a presses the first piece 72 of the rod 70. Therefore, the first piece 72 of the inserted rod 70 cannot be removed from the mounting groove 41 of the base member 40, so that the rod 70 can be attached to the base member 40. In this way, the rod 70 can be attached to the base member 40.

  Further, the base member 40 is provided with a rattling prevention mechanism 50 for preventing rattling against the ruler plate 2. The backlash prevention mechanism 50 includes a backlash prevention dial 51 that is rotated by a user. A screw shaft portion (not shown) is provided at the center of the lower surface of the rattle prevention dial 51, and a cylindrical operation portion (not shown) is provided integrally therewith.

  On the other hand, the base member 40 is provided with an operation recess 49 for accommodating the operation portion of the rattle prevention dial 51. A screw hole (not shown) is provided at the center of the operating recess 49, and the screw shaft portion of the rattle prevention dial 51 is fastened to the screw hole. Therefore, when the anti-rattle dial 51 is operated to rotate, the anti-rattle dial 51 itself is displaced up and down. An elastic buffer member (not shown) having elasticity is sandwiched between the operating portion of the rattling prevention dial 51 and the bottom of the operating recess 49.

  The operation recess 49 is communicated with the guide recess 44 through a window (not shown) provided in a part of the periphery of the operation recess 49. Therefore, when the rattling prevention dial 51 is rotated in the screw shaft tightening direction, the screw shaft portion is tightened into the screw hole and the operating portion is displaced downward, whereby the buffer member is radially outward (in the diameter expanding direction). To be spread. When the buffer member is spread out, a part thereof protrudes into the guide concave portion 44 through the window portion, and this is elastically pressed against the side surface of the guide convex portion 30 of the ruler plate 2.

  In the rattling prevention mechanism 50 provided on the base member 40, the guide concave portion 44 with respect to the guide convex portion 30 is operated by rotating the rattle prevention dial 51 and elastically pressing the buffer member against the guide convex portion 30 of the ruler plate 2. As a result, the base member 40 on the ruler plate 2, and thus the straight movement without the backlash of the portable marvel 4 can be realized. The pressing force of the buffer member can be adjusted by the rotation operation amount of the rattle prevention dial 51, and thereby the moving operation force (sliding resistance) on the ruler plate 2 of the portable marnoco 4 can be adjusted. The base member 40 is configured in this way.

  Further, the connector 60 is provided with a recess 61 on the upper surface thereof over the entire length (see FIGS. 5 to 7). Long holes 61b are provided on both sides of the concave surface 61a of the concave portion 61, respectively. The width of the long hole 61 b in the short direction is set longer than the width of the recess 61. In addition, the width length of both wall surfaces of the recessed part 61 in which this long hole 61b is provided is set so that it may correspond with the width length of the transversal direction of the long hole 61b. That is, a constriction 61c corresponding to the long hole 61b is provided on both wall surfaces of the recess 61 where the long hole 61b is provided. The connector 60 is configured in this way.

  When both ends of the connector 60 are inserted into the mounting grooves 45 of the base member 40 and the fixing screws 47 are screwed into the nuts 48 and tightened, the base member 40 is connected to both ends of the connector 60. (See FIGS. 4 to 5). The ruler adapter 3 is composed of a base member 40 that forms a pair before and after the connector 60 and a connector 60 that connects the base members 40.

  The fixing levers 28 are tightened in a state in which the second piece portions 73 of the two rods 70 of the ruler adapter 3 configured as described above are inserted into the ruler mounting portions 26 of the portable marnoco 4 respectively. Then, the tip of each fixing lever 28 that has advanced from a through hole (not shown) presses each second piece 73 of the two rods 70. Therefore, the second piece 73 of the inserted two rods 70 cannot be removed from the respective ruler attaching portions 26 of the portable maroon saw 4, so that the two rods 70 can be attached to the portable maroon saw 4. In this way, the two rods 70 can be attached to the portable marnoco 4. As a result, the ruler adapter 3 can be attached to the portable marnoco 4.

  Then, the base members 40 are placed on the upper surface of the ruler plate 2 in a state where the guide convex portions 30 of the ruler plate 2 are fitted into the guide concave portions 44 of the base members 40 of the ruler adapter 3 attached to the portable marnoco 4. By placing the base members 40 so as to be in an overlapped state, both the base members 40 and thus the portable marvel 4 can be accurately linearly moved (straightly moved straight even at a long distance) along the guide convex portion 30 of the ruler plate 2. .

Both base members 40 are brought into contact with the sliding material 31 of the ruler plate 2, and the base portion 10 of the portable marnoco 4 is brought into contact with the sliding material 32, so that both the base members 40 and the portable device are carried. The marunoco 4 can be smoothly linearly moved on the ruler plate 2. Further, the ruler plate 2 is placed on the upper surface of the wood W in a state where the anti-slip material 33 attached to the lower surface of the ruler plate 2 is in contact with the wood W, thereby preventing the position deviation of the ruler plate 2 with respect to the wood W. This also makes it possible to smoothly move the portable marnoco 4 in a straight line, and as a result, it is possible to easily perform accurate cutting (cutting straight even at long distances).

  In the ruler adapter 3, when the tightened fixing screws 47 are loosened, the nut 48 can move in the long hole 61 b, so that both the base members 40 and the connector 60 are continuously relatively moved along the front-rear direction. Can be made. That is, the relative distance between the base members 40 can be continuously adjusted along the front-rear direction (see FIG. 8). This adjustable range L is a range in which the nut 48 can move in the long hole 61b. Therefore, when it is desired to ensure the wide adjustable range L, the length of the long hole 61b may be increased.

  When the base members 40 and the connector 60 can be continuously moved relative to each other in the front-rear direction in this way, the relative distance between the two rods 70 of the base members 40 is continuously increased along with the relative movement. Can be adjusted. Even if the tightening of the fixing screw 47 is loosened, the screwed nuts 48 are caught on both edges of the recess 61, so that the connector 60 does not fall off the base member 40 (see FIG. 6). Therefore, the continuous adjustment of the relative distance between the base members 40 can be performed smoothly.

  The ruler adapter 3 according to the embodiment of the present invention is configured as described above. According to this configuration, the ruler adapter 3 includes the two rods 70. The relative distance between the two rods 70 can be adjusted continuously. Therefore, the interval between the two rods 70 can be matched to the interval between the ruler attachment portions 26 regardless of the interval between the ruler attachment portions 26 of the portable marnoco 4. Therefore, unlike the prior art, the ruler adapter 3 does not lack the versatility of attachment to the portable marnoco 4. As a result, in this ruler adapter 3, versatility of attachment to the portable marnoco 4 can be enhanced.

  Further, according to this configuration, the continuous adjustment of the relative distance between the two rods 70 is performed by the continuous adjustment of the relative distance between the base members 40 that form a pair in the front-rear direction. Therefore, the relative distance between the two rods 70 can be adjusted stably.

  Further, according to this configuration, the continuous adjustment of the relative distance between the base members 40 that form a pair in the front-rear direction is performed by continuously adjusting the relative distance between each base member 40 and the connector 60. . For this reason, it is possible to double the adjustment of the continuous adjustment of the relative distance between the base members 40. Accordingly, even if the ruler adapter 3 has a compact configuration, a wide continuous adjustment range of the relative distance between the two rods 70 can be secured.

  The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.

  In the embodiment, “portable marnoco 4” has been described as an example of “portable processing machine”. However, the present invention is not limited to this, and may be “jigsaw”, “router”, or the like.

  In the embodiment, “two rods 70” is described as an example of “at least two rods”. However, the present invention is not limited to this, and any number of rods may be used as long as there are three, four, or a plurality of rods. In that case, the number of base members 40 and connectors 60 also increases as the number of rods 70 increases.

  Moreover, in the Example, the form which both the base members 40 with which the two rods 70 were attached was relatively movable was demonstrated. However, the present invention is not limited to this, and the two rods 70 themselves may be relatively movable. In that case, both the base members 40 do not need to be comprised by another member, and may be comprised by one member.
